Authentication codes for non-trusting parties obtained from rank metric codes
Publikation/Tidskrift/Serie: Designs, Codes and Cryptography
In this paper we introduce a new way of constructingA 2-codes, i.e., authentication codes that protect against deceptions from an opponent and additionally also protect against deceptions from the transmitter and the receiver. The construction uses codes for the rank metric, a well-known field in coding theory. The construction gives improved performance compared with previous work and it also gives an opportunity to use unequal authentication protection when the participants are unequally trusted.
